๐งฉ What is AW Bollinger Bands EA?
The AW Bollinger Bands EA is a fully automated trading robot designed for MetaTrader 4 (MT4) that capitalizes on the statistical properties of the Bollinger Bands indicator. It is built on the core principle of Mean Reversionโthe idea that price extremes are temporary and will eventually return to the average (middle band).

๐งฉ Lot Settings โ Risk & Money Management
โก๏ธ Size of the first order: 0.01
- Very small initial lot size.
- Suitable for small accounts, cent accounts, or conservative starting exposure.
- Helps reduce early drawdown when grid averaging begins.
โก๏ธ Enable Autolot calculation: true
- Lot size is automatically calculated based on account balance.
- Improves long-term stability compared to fixed lots.
โก๏ธ Autolot deposit per 0.01 lots: 5000.0
- For every $5,000 balance, the EA trades 0.01 lot.
- This is a conservative autolot ratio, significantly lowering risk.
๐ Conclusion (Lot Settings):
The EA uses safe and scalable money management, making it more suitable for long-term trading compared to aggressive grid systems.

๐งฉ Averaging Settings โ Grid & Recovery Logic

- Each new averaging order increases lot size by 1.5x.
- This is a moderate martingale multiplier, not overly aggressive.
